How do you find the minimum number of workstations?

Calculate the theoretical minimum number of workstations. NUMBER OF WORK STATIONS = ( SUM OF TOTAL TASK TIMES) / (CYCLE TIME)= 70 min's / 15 min's = 4.67 ≈5 (rounded) Number of Task Following Tasks STEP 4.

In this regard, how do you calculate minimum cycle time?

a. Minimum cycle time = length of longest task, which is 2.4 minutes. Maximum cycle time = ? task times = 18 minutes. b.

Subsequently, question is, how do you calculate the cycle time of an assembly line? The classic calculation for takt time is:
  1. Available Minutes for Production / Required Units of Production = Takt Time.
  2. 8 hours x 60 minutes = 480 total minutes.
  3. 480 – 45 = 435.
  4. 435 available minutes / 50 required units of production = 8.7 minutes (or 522 seconds)
  5. 435 minutes x 5 days = 2175 total available minutes.

how do you calculate delay in balance?

The balance delay is the percentage of wasted time or 100% - the efficiency. In this example, it is 4 (the idle time)/30 or . 1333, which is also determined by 1-. 8667.

How do you measure cycle time?

So the simplest way to measure the cycle time of an assignment is to count the number of days it spent being worked on. In other words, if you start a task on the 15th of April and complete it on the 25th of April, then the cycle time is 10 days.

What is the idle time per cycle?

If, for example, a process consists of two steps each claiming 20 seconds, the total labor content is 40 seconds. Idle time: The idle time is defined as cycle time minus processing time.

What is cycle time production?

Manufacturing cycle time refers to the time required or spent to convert raw materials into finished goods. It is also known as throughput time. Technically, it is the length of time from the start of production to the delivery of the final products.

How do you calculate maximum daily output?

Determine how long it takes to produce one unit of product, then divide the daily plant capacity in hours by the time it takes to produce a product to arrive at the daily production capacity. For example, say it takes a worker half an hour (0.5 hours) on a machine to make a widget and the capacity is 800 machine hours.

How do you calculate idle time?

Once you find the actual hours for each worker, add them up for the group whose total idle time you want to calculate. Subtract the total number of actual hours worked from the standard hours. The difference is the idle time.

What is a cycle time in management?

Definition of Cycle Time: The total time from the beginning to the end of your process, as defined by you and your customer. Cycle time includes process time, during which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is spent waiting to take the next action.

What is cycle time in garment industry?

Some people say Cycle Time is the time between two successive deliveries, while others believe it is the time between initiation and delivery. In simple terms, Cycle time is the time starting when operation begins to the point of time when the operation ends.

What is assembly line balancing?

Assembly line balancing can also be defined as assigning proper number of workers or machines for each operations of an assembly line so as to meet required production rate with minimum or zero ideal time.

What is balance delay?

<P>Balance delay time is the amount of idle time on production assembly lines caused by the uneven division of work among operators or stations. It is related to the extent and way the total task is subdivided. In this paper the problem of balance delay is treated empirically and analytically.

How do we calculate efficiency?

The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%. Wout = the work or energy produced by a process. Units are Joules (J).

Ahlame Areosa


How do you determine the number of stations?

Number of stations is calculated by dividing total work content (in your example 200 hrs) by takt time (5 days = 40 hrs). So 200/40 = 5. If the machine is big, you could consider working with 2 operators at the same time, then de number of station is (200/2)/40 = 3 (because you can't have half a workstation.

How do you calculate line efficiency?

The line efficiency formula is the number of hours when a high-volume pick-and-place machine is putting parts on the printed circuit board, divided by the number of hours where you are staffing the SMT assembly line. Put more simply, it is the placement time hours divided by the staffed time hours times 100.

What is the goal of LINE balancing?

Line Balancing is a strategy to level the workload across all processes in a workstation to remove excess capacity. It involves setting an optimal rate of production for required materials to meet within a particular time frame. The goals of line balancing are as shown below: 1.

What is meant by takt time?

Takt is the German word for the baton that an orchestra conductor uses to regulate the tempo of the music. Takt time may be thought of as a measurable beat time, rate time or heartbeat. In Lean, takt time is the rate at which a finished product needs to be completed in order to meet customer demand.

Smahan Guedelha


How do you calculate the number of operators needed?

Takt time and cycle time determine the number of operators. Dividing the total cycle time needed to produce a product by the takt time yields the number of operators required to meet customer demand. In reality, this calculated number is often low, as processes are seldom perfectly balanced.

What is the efficiency of the balanced line?

- Line efficiency is the ratio of work stations time to the cycle time multiplied by the number of stations and - Smoothness index is an index that becomes the relative refining index of an assembly line balance. The minimum value of the smoothness index is 0 which indicates a perfect balance.
